Abstract:

目的:探讨半量替罗非班在急性ST段抬高心肌梗死(STEMI)患者行急诊冠状动脉介入治疗(PCI)术后应用的疗效和安全性。方法:入选2014年1月至10月因STEMI就诊,并行急诊PCI治疗患者共120例。于术前采用随机数字法将患者分为标准剂量组(A组,60例)和半量组(B组,60例)。术前常规服用阿司匹林300mg、氯吡格雷600mg,推注肝素70IU/kg,术中应用替罗非班10μg/kg,对于血栓负荷重的患者,应用机械抽吸装置,保证术后心肌梗死溶栓治疗血流分级(TIMI)3级血流。术后两组均联合给予低分子肝素皮下注射,比较两组患者的基线资料、术后90min ST段回落不良率、肌酸激酶同工酶(CK-MB)及肌钙蛋白I峰值、左心室射血分数、主要不良心血管事件(靶血管重建、再次心肌梗死、支架内血栓、心力衰竭、死亡)和出血事件。结果:两组患者的基线资料差异无统计学意义(P>0.05)。术后90min ST段回落百分比(sumSTR)、肌酸激酶同工酶及肌钙蛋白I峰值、左心室射血分数及主要不良心血管事件差异均无统计学意义(P>0.05),标准剂量组术后发生主要出血1例,小出血1例,轻微出血5例(鼻出血2例,牙龈出血2例,痔疮出血1例),半量组术后发生轻微出血1例为牙龈出血,术后出血的差异有显著统计学意义(P=0.03)。结论:急诊PCI术后TIMI血流3级的STEMI患者半量应用替罗非班可以安全有效降低心血管事件,且有助于减少出血并发症
